Household and similar electrical appliances - Test code for the determination of airborne acoustical noise - Part 2-13: Particular requirements for range hoods
1.1General
Replacement:
These particular requirements apply to electrical range hoods (including their accessories and
their component parts) for household and similar use.
By similar use is understood the use in similar conditions as in households, for example in
inns, coffee-houses, tea-rooms.
These particular requirements apply to range hoods intended for filtering the air of the room or
for exhausting the air out of the room. It also applies to range hoods with an external fan.
These particular requirements do not apply to:
- range hoods for industrial or professional purposes.
Intensimetric method for the determination of sound power levels shall not be used for the
purpose of verification.
1.1.2 Types of noise
Addition:
The method is applicable to any source for which a physically stationary measurement surface
can be defined, and on which the noise generated by the source is stationary in time (as
defined in Clause 3), therefore it is not suitable for sources of impulsive noise consisting of
short duration noise bursts. This method is not suitable if the source under test has significant
noise over 6,3 kHz in one-third-octave band centre frequencies and over 4 kHz in one-octave
band centre frequencies.
1.1.3 Size of the source
Rep/acement:
The size of the noise source is unrestricted. The extent of the source is defined by the choice
of the measurement surface.
